WIRING-ER.

Application filed February 17, 1922. Serial No. 537,144.

My invention has reference to wringers of the type used in connection with washing'machines for wringing clothes, and seeks to provide an improved wringer of this character; to lessen the cost of manufacture; to minimize the weight; and to embody same in a more compact anddesirable form than wringers which have heretofore been provided.

Other objects of my invention are to provide a wringer which may be readily constructed of sheet metal or stamping; to simplify the construction and facilitate assembling; to afford a more desirable location for the tension spring; to house the spring in the base of the wringer; to afford an improved tension release; to permit unlimited separation of the rolls when the tension is released; to mount the upper roll in a frame which,is entirely removable from the base or main frame which carries the lower wringer roll; and in general, to provide a wringer which is better adapted for use in connection with power washing machines than wringers heretofore provided.

Referring to the drawings, the reference numeral 1 indicates the lower wringer roll and 2 the upper wringer roll, the former of which is journaled in the main frame of the wringer and the latter of which is journaled in a removable frame, which slides into the upper end of the mainframe and is held downwardly therein by a spring, so

as to afford a yielding tension between the I rolls.

' The main frame comprises an inverted channel member or base 3, preferably of sheet metal, which is rolled or stamped, so as to have a flat top 4 with a flange 5 along each side and depending at right angles thereto. Mounted at one end of the channel base 3, is a pair of sheet metal guides 6, which are reversely arranged on opposite sides respectively of the base 3, and each has a plate portion at the lower end extending'down along the respective side'flange 5 and secured thereto by riveting, as inditended downwardly to the lower extremities of the side flanges 5 of the base 3, as shown in Figs. 5 and 6, and these flanges 8 as well as the flanges 9, extend upwardly from the top of the base 3, so as to form guideways into the upper ends of which the ends of the frame which carries the upper wringer roll are slidably engaged. A bearing block 11 is placed in the bottom of this guideway upon the top 4 of the base member 3, as shown in Fig. 7, and is secured in place by a bolt 12, which clamps the bearing block between the guides 6 and serves to hold the latter in the required spaced relation.

Spaced from the guides 6 and secured to the base 3 in a similar manner, are a pair of guides 13, which have a doubled back, 3

portion 14 along the edges similar to the portion 10 of the guides 6, and also flanges 15 and 16 similar to the flanges 8 and 9 of the guides 6, but spaced farther apart, as shown in Fig. 4. A bearing block 17 is secured between the guides 1313 by a bolt 18 so as to leave a-gear space, 19 between the bearing block 17 and the flanges 16. Each bearing block 11 and 17 has a semi-circular cavity 20 and 21 respectively in the upper end in which the shaft 22 of the lower wringer roll 1 is engaged, said shaft being extended out beyond the guide 13 to receive a driving connection for operating the wringer. The channel member or base 3 is likewise extended beyond the guides 13 and.

servesto mount the wringer on a support.

The frame which carries the upper roll 2 is'also preferably formed of pressed or stamped metal and comprises an inverted channel 24:, having the ends turned down, as indicated at 25, and provided with a bearing block 26 at each end, secured in place by a rivet 27. Each bearing block projects down below the end of the channel member 24 and is enclosed in a sheet metal housing 28, which is fastened to the bearing block 26 by screws 29, and each bearing block has a bearing slot 30 in the lower end to receive the ends of the shaft 31 of the upper roll 2, said shaft being retained in the bearing slots 30 by the lower walls 32 of the housings 28, which extend across the open lower end of the'slot. The housing 28 is of suitable form and size to slidingly engage into the open upper end of the guideway formed by the guides 66 or 13-13 respectively,

' the inner flanges 9 and 16 of said guideway being preferably terminated sufficiently be low the upper ends of the guideway to facilitate insertion of the upper frame, and the shaft 31 of the upper roll has a gear 33 fixed thereon which meshes with a gear 34, which is fixed on the shaft 22 of the lower wringer roll, these gears being positioned in the gear chamber 19 of the guideway 13-13 between the bearing block 17 and the inturned flanges 16.

It is necessary for the upper roll 2 to be held at a tension against the lower roll 1.

and to accomplish this purpose and alsb lock the upper frame 24 in the lower or main frame of the wringer, there are plates 35 and 36 respectively at the opposite ends of the wringer frame, the former of which is confined to slide between the bearing block 11 and the. flanges 8 of the guides 6, and the latter of which is confined to slide between the bearing block 17 and the flanges 15 of the guides 13, and these plates 35 and 36 extend upwardly along the ends of the upper frame 34, as shown in Fig. 2, and have perforations 38 engaged by locking rods 39, which latter are mounted in the upper frame 24. These rods 39 are connected at their innerends to a plate 40 at o posite sides of the stem 41 to which the p ate 40 is secured, and this stem extends up through the member 24, the latter being provided with a depending sleeve or bearing 42 for pivotally supporting the stem 41, and the upper projecting end of this stem is provided with a handle 43 for operating the stem 41 and plate 40 to simultaneously projeet the rods 39 outwardly, as shown by full lines in Fig.3, or to withdarw same'in-,

wardly, as shown by dotted lines in said figure. The outer ends of these rods 39 are loosely mounted in corresponding apertures 44 and 45 of the bearing block 26 and end plate 25 of the member 24, and are adapted when projected outwardly to engage in the apertures 38 of the plates 35 and 36. The lower ends of the plates 35 and 36 project down below the top 4 of the channel member 3; between the side flanges 5, the top 4 being" provided with a slot 46, through which the plate 36 passes, and each of these plates has a transverse slot 47 at the lower end which is engaged by the respective end of a plate spring 49, which extends lengthwise within the channel member 3. A cap .screw 50 is threaded through the spring 49 intermediate of its ends, and engages at its upper end against a bridge 51, which is secured to the under side of the top 4 of the channel member 3, said cap screw being adjustable to regulate the tension of the spring 49 to exert the required downward pull on the plates 35 and 36, to afford the required pressure of the upper roll 2 against the lower roll 1.

Vhen the locking rods 39 are released from the apertures 3810f the plates 35 and 36, the latter are pulled downwardly by the tension of the spring 49, somewhat below the ends of the locking rods 39, so that the latter will not readily re-engage therein. To facilitate re-engagement of the locking rods 39 with the apertures 38, I have provided a rod 52, which is mounted in bearings 53 on the under side of the top 4 of the channel member 3, and has a handle 54 projecting beyond the end of the wringer, whereby the rod 52 is rotated in its bearings. This rod projects through a vertical.

slot 55 in each plate 35 and 36, and is notched at 56 where it passes through each plate and 36, so that the remaining portion of the rod within the notch 55 serves as a cam. When the rod 52 is turned to the position shown in Fig. 2, the notches 56 are at the upper side of the rod and afford clearance between the upper end of the notch 55 and the bottom ofvthe notch 56,

so that the spring 49 is free to exert a tension through the plates 35 and 36 on the upper frame 24 and hold the roll 2 down against the lower roll 1. When, however,

the rod 52 is turned to the position shown in Fig. 1, the notches 56 are turned downwardly, and the solid portion of the shaft serves as a cam, which acts against the upperend of the slot 55 and lifts the plates 35 and 36 against the tension of the spring 49, so that the apertures 38 in the plates 35 and 36 are in position to be readily engaged by the ends of the locking rods 39 when the upper frame 24.is set in place in the top of the main frame.

In assembling the wringer, therefore, the

shaft 52 is turned to the position shown in as toproject the rods 39 outwardly through the aperatu'res 38, thereby locking the frame 24 onto the upper end of the plates 35 and 36. The rod 52 is then rotated to the position shown in Fig. 2, which releases same from engagement with the plates 35 and .36 and permits the tension of the spring 49 to be communicated to the upper frame 24 for holding the upper roll 2 down against the lower roll 1.

lVhen it is necessary to release the roll, the. handle 43 is merely given a quarter turn movement so that the rods 39 are withdrawn from the apertures 38 of the plates 35 and 36, thereby leaving the upper frame 24 free in the upper end of the main frame so that it may be entirely withdrawn or removed from said main frame. The release of the locking rods 39 does not impart any movement or throw to the upper frame 24, as the plates 35 and 36 are merely impelled downwardly by the tension of the spring 49, said downward movement being arrested by stop pins 57, with which the ends of the spring 49 come into engagement and these stop pins prevent impact of the plates 35 and 36 against the shaft 52, The upper ends of the plates 35 and 36 are preferably beveled, as indicated at 58, to facilitate insertion of the upper frame, said plates being alike in all respects except that the latter has a vertically elongated slot 59, through which the shaft 22 extends, this slot being sufficiently long to permit the necessary elevation of the upper frame 24 for unrestricted operation of the wringer.

This wringer has a reversible drain board mounted under the lower roll 1, with a flange 61 ateach end, having a slot 62 engaged respectively on the pins 63 and 64 carried by the bearing blocks 12 and 17 ,respectively, the slots being provided so as to permit the drain board to be drawn laterally toward either side of the wringer and tilted downwardly at that side for draining the water from the clothes, as they are passed through the wringer, back into the tub.

This wringer is designed so that the frame parts are constructed. almost solely of sheet metal, thereby minimizing the cost of same and affording a light weight structure, and furthermore, the assembling is simplified so as to further reduce the costof construction and render the parts easily accessible for replacement and repairs, The placing of the spring in the bottom of the wringer frame renders it possible to construct the wringer in a more compact form than ,w'ringers heretofore provided, and provides a light upper frame which is easy to handle.
